Today, Elsevier is announcing that it has acquired SSRN, the preprint and publishing community that focuses on social sciences and law. Among other things, the SSRN acquisition is another step in Elsevier’s path towards data and analytics. In a number of ways, Mendeley is the linchpin for this acquisition. More generally, this acquisition plainly indicates Elsevier’s interest in the open access repository space. Finally, universities, their libraries, and other publishers, should have on their minds some of the policy and governance issues around the data that Elsevier is accumulating and the uses to which they may be put.
